Charlatán Culirrufo Pterorhinus gularis

A large laughingthrush with a heavy black bill. Note black mask on face, yellow throat, and reddish belly. Similar to Yellow-throated Laughingthrush, but Rufous-vented Laughingthrush is bigger and darker above, with contrastingly pale feet. Extremely shy and skulking, it often moves in flocks of ten or more birds, foraging in thick undergrowth and on the ground in evergreen forests. Calls include sweet whistles and chattering.
